98 SIXTEENTH REPORT ON THE CABINET OF NAT. HISTORY. 



Perry in the State of Maine, and preserved in the collection of 

 the Natural History Society of Portland. The whole of the plants 

 thus described I summed up in the paper last mentioned as con- 

 sisting of 21 species, belonging to 16 genera, exclusive ot genera 

 like Sternbergia and Lepidostrobus, which represent parts of 

 plants only. 



In the past summer I visited St.John, and, in company with 

 Messrs. Matthkw and Hartt, explored the localities of the plants 

 previously discovered, and examined the large collections which 

 had been formed by those gentlemen since the publication of my 

 previous paper. The material thus obtained proving unexpectedly 

 copious and interesting, I was desirous of having opportunities 

 of fuller comparison with the Devonian Flora of New- York State ; 

 and, on application to Prof. Hall, that gentleman, with consent 

 of the Regents of the University of New- York, kindly placed in 

 my hands the whole of his collections, embracing many new and 

 remarkable forms. Professor C. H. Hitchcock, State Geologist of 

 Maine, had in the mean time further explored the deposits at 

 Perry, and has communicated to me three new species discovered 

 by him. The whole of these collections, amounting in the whole 

 to more than sixty species, constitute an addition to the Devonian 

 Flora equal in importance to all the plants previously obtained 

 from rocks of this age, and establish for some of the species a 

 very extensive distribution both geologically and geographically : 

 they allow, also, more satisfactory comparisons than were here- 

 tofore practicable to be instituted between the Devonian Flora 

 and that of the Carboniferous period. 



I shall first shortly notice the geological character of the lo- 

 calities, with lists of the fossils found in each, and shall then 

 proceed to describe the new species. 



Notices of the Localities of the Devonian Plants. 



1. State of New-York. The geology of this State has been so fully illu- 

 strated by Professor Hall and his colleagues, and the parallelism of its 

 formations with those of Europe has been so extensively made known by 

 Murchison and others, that it is only necessary for me to state that the 

 fossils entrusted to me by Prof. Hall range from the Marcellus shale to 

 the Catskill group inclusive, and thus belong to the Middle and Upper 

 Devonian of British geologists. The plants are distributed in the sub- 

 divisions of these groups as follows :
